Abstract

Accommodation may depend upon such factors as age and refraction. The authors measured and analyzed lens thickness and anterior chamber depth of an emmetropic group(7 persons, 14 eyes) and a myopic group(8 persons, 16 eyes) in adult of second decade during near fixation(30 cm), and weak cycloplegic state with 1% tropicamide eye drop using the Storz OMEGA Compuscan.There were statistically significant difference between accommodation and cycloplegic state in lens thickness and anterior chamber depth(p<0.0l, p<0.05). In the myopic group there was negative correlation between lens thickness and axial length and between lens thickness and anterior chamber depth(r=-0.60(p<0.0l), r=-0.48(p<0.05)). The authors determined that there was not the same difference value of lens thick ness as that of anterior chamber depth between accommodation and cycloplegic state; being 0.04 mm(25%) in emmetropic group and 0.02 mm(22%) in myopic group.
